CEOI 2008 Online Competition

Parallel to CEOI 2008, the CEOI 2008 Online Competition will take place, during the same competition hours and with the same competition tasks. We would like to invite everybody to participate.

The competition will take place on Tuesday, July 8th 2008, and Thursday, July 10th 2008, from 08:30 CEST to 13:30 CEST (06:30 UTC to 11:30 UTC). Since it will be exactly in sync with the local competition, it might be a few minutes late, but we hope to start on time.

All relevant sections of the rules apply. The results will be available in the system shortly after each competition session and will eventually be published on the homepage. No awards will be given. Tasks will be available in English only.

You are welcome to post your clarification requests during the first two hours of the competition in #ceoi2008 in the IRCnet. Please do not share any ideas during the contest. Use private messages if unsure. (To connect to the IRCnet, use e.g. a web client.)

Results of the Online Competition

Results of the local competition, problem descriptions and short spoilers are available here.
